Initially two blocks attached to separate springs are just touching at the equilibrium point B as in Figure (a) below. The mass of each block and the spring constant of each spring is noted in the figures. The springs are then compressed by the amounts shown in Figure (b). The blocks are released at the same instant and the surface is frictionless. Where will they hit?
